Episode 105: Jo Malone at Chelsea, misbehaving wisteria, tomato questions answered.

As this year’s gardens take shape, we visit the RHS Chelsea Flower Show to meet the designers. These include the brand-new, sensory Feel Good Gardens, created in conjunction with BBC Radio 2 DJs and celebrities including Jo Whiley and Jo Malone. Plus we have seasonal expert advice on questions including poorly-looking tomato plants and a wisteria whose flowers have changed colour.
